Allot of questions are pure Electronics theory questions. People trying to drive motors with GPIO pins or running out or power.
They require to build specialist circuits, that the Pi will drive. In this case it does not matter if they use a Pi, Arduino or PIC.
But they come here looking for help instead of electronics exchange because they are using a Pi to do this.
There is only a "belongs on Linux/Ubuntu". Should we have a "belongs on Electronics Exchange" ?
